Macroglenes japonicus sp. nov.

(Fig. 27)

Diagnosis. Body black, without metallic reflections; clypeal margin not incised (cf. Figs 1–2); only F5 large, with sensilla (cf. Fig. 5); mesosoma slightly but distinctly arched dorsally; pecten regular, extending slightly less than 2/3 length of hind tibia (cf. Fig. 14); forewing with basal cell bare and with bare area between R and apical margin (cf. Fig. 22, but less extended); ovipositor sheaths moderately expanded, hypopygium reaching tip of gaster (Fig. 27).

Description. Female.

Body length: 1.25 mm.

Color. Body black, without metallic reflections. Eye light red. Mandible yellowish-brown. Antenna: scape and pedicel brown, F1–F4 yellowish-brown, F5 and clava light brown. Legs brown, with knees, apices of tibiae and tarsi yellowish. Tegula and venation brown, wings hyaline.

Head. In frontal view about as high as wide. POL about 1.6X OOL. Eye height about 1.5X length. Malar space about 0.3X as long as eye height. Scape distinctly shorter than eye height and about equal to eye length; combined length of pedicel and flagellum shorter than head width; pedicel length in lateral view about 1.6X width; F1–F4 anelliform, without sensilla, their combined length distinctly shorter than length of pedicel and only slightly longer than length of F5, the latter width about 1.6X length and provided with sensilla; clava about as long as combined length of pedicel and F1–F5, twice as long as broad.

Mesosoma. Length about 1.7X width and about twice height, slightly but distinctly arched dorsally. Scutellum almost flat but making a distinct angle with propodeum. Forewing length about 2.4X width; M:R:P = 29:4.5:5; basal cell bare, with 4 hairs on basal vein; speculum quite wide, at least in anterior part, extending to R; stigma small, subtriangular; forewing on upper side with glabrous area beyond R extending towards apical margin, the glabrous area partially effaced by hairs on ventral side. Pecten regular, extending on slightly less than 2/3 as long as hind tibia.

Gaster (Fig. 27). Including ovipositor sheaths, length about 3X width and about 1.3X as long as mesosoma, laterally compressed. Ovipositor sheaths about 1/3 length of hind tibia. Hypopygium slightly exceeding tip of gaster.

Male. Unknown.

Material examined. HOLOTYPE (Ψ): JAPAN: ‘ JAPAN: Honshu, Tochigi, Nishinasuno N.G.R.I., 500 m, 10. VIII. 1989, M. J. Sharkey, sweep’ ( CNC).

Comments. The new species most closely resembles M. chalybeus , but clearly differs in its mesosoma which has a distinct angle between a rather flat scutellum and propodeum.

Distribution. Japan.

Hosts. Unknown.
